Vue2.0史上最全入坑教程(完)—— 实战案例

我们书接上文,已经定义了两个组件(list、commonFooter、homeHeader.vue),接下来写home.vue:
<template lang="html">
  <div class="container">
    <home-header></home-header>   <!--  展示引入的header组件 -->
    <div class="content">
      <ul class="cont-ul">
          <!-- list组件展示区,并用v-for来将数据遍历,:xx="xxx" 是用来给子组件传递数据的 -->
        <list v-for="item in items" :price="item.price" :title="item.title" :img="item.img"></list>
      </ul>
    </div>
    <common-footer></common-footer>  <!--  展示引入的footer组件 -->
  </div>
</template>
<script>
import HomeHeader from '../components/HomeHeader'   /* 本页面中用到了HomeHeader组件,所以就需要在这里引入一下 */
import CommonFooter from '../components/commonFooter'
import List from '../components/list'
export default {
  data () {
      return {
          items: []   /* 定义一个空数组数据items */
      }
  },
  components: {
    HomeHeader,
    CommonFooter,
    List
  },
  created () {   /* 这个是vue的钩子函数,当new Vue()实例创建完毕后执行的函数 */
      this.$http.get('/api/goods').then((data) => {   /* 调用vue的ajax来请求数据,promise语法,并用es6的箭头函数 */
      this.items = data.body.data;
      })
  }
}
</script>

<style lang="css" scoped>
  .container {
    width: 100%;
    margin: 0 auto;
  }
  .content {
    margin-bottom: 1.8rem;
  }
  .cont-ul {
    padding-top: 0.5rem;
    background-color: #ccc;
  }
  .cont-ul::after {
    content: '';
    display: block;
    clear: both;
    width: 0;
    height: 0;
  }
</style>

3. 商品详情页goodsDetail.vue:

a). DetailHeader.vue

<template lang="html">
  <div class="head">
    <div class="header">
      <a href="javascript:;" class="go-back" @click="goBack">返回</a>
      <h4 class="header-cont">商品详情页</h4>
    </div>
  </div>
</template>

<script>
export default {
  methods: {
    goBack () {
      window.history.back();
    }
  }
}
</script>

<style lang="css" scoped>
  .head{
    height: 2rem;
  }
  .header{
    width: 100%;
    height: 2rem;
    position: fixed;
    left: 0;
    top: 0;
    background-color: #fff;
    border-bottom: 2px solid #ccc;
  }
  .header .go-back {
    width: 2rem;
    height: 2rem;
    text-align: center;
    color: #ccc;
    font-size: 0.8rem;
    float: left;
    line-height: 2rem;
    margin-left: 1rem;
    position: absolute;
    left: 0;
    top: 0;
  }
  .header .header-cont {
    width: 100%;
    text-align: center;
    line-height: 2rem;
    font-size: 1.2rem;
  }
</style>

b). goodsDetail.vue

<template lang="html">
  <div class="detail">
      <detail-header></detail-header>
      <p class="site-title">树懒果园 泰国进口大金煌芒果</p>
      <p class="site-cont">5斤装,约2-4个果,大!!!甜!!!</p>
      <common-footer></common-footer>
  </div>
</template>

<script>
import DetailHeader from '../components/DetailHeader'
import CommonFooter from '../components/commonFooter'

export default {
  data () {
    return {

    }
  },
  components: {
    DetailHeader,
    CommonFooter
  }
}
</script>

<style lang="css">
  .detail {
    padding: 0.25rem;
    font-size: 12px;
  }
  .detail > img {
    display: block;
    width: 80%;
    margin:  0 auto 0.5rem;
  }
  .detail > p {
    font-size: 1.1rem;
    line-height: 1.5rem;
    text-align: left;
    padding-bottom: 0.5rem;
  }
  .detail > p.site-title {
    color: #ff8000;
  }
  .detail > p.site-cont {
    color: #666;
    font-size: 0.9rem;
  }
</style>
